御装置。In an internal combustion engine in which a throttle valve is arranged in an intake passage that connects a compressor of a turbocharger and an engine cylinder, a bypass passage that connects an intake passage upstream of the throttle and an intake passage downstream of the throttle valve; Negative pressure diaphragm type flow control valve arranged,
The supercharging chamber is equipped with a throttle sensor for detecting the idle link position of the throttle valve and a sawtooth supercharging pressure sensor installed in the intake passage for detecting supercharging pressure, and the flow control valve is isolated by a diaphragm. and a pressure control chamber, the bypass passage is configured to open when the pressure in the boost pressure chamber becomes higher than the pressure in the pressure control chamber by a predetermined constant value, and The pressure chamber is connected to the intake passage upstream of the throttle valve, and the pressure control chamber is connected to the intake passage downstream of the throttle valve via a conduit, and within the iW, an atmosphere is provided that responds to the throttle sensor and the boost pressure sensor. A turbocharged internal combustion engine is provided with a switching valve that can communicate with the pressure control chamber and connects the pressure control chamber to the intake passage when the throttle valve is in an idling position and the boost pressure is higher than a predetermined set pressure. deceleration control device.
